Comments on real tachyon vacuum solution without square roots

High Energy Physics - Theory 2018-01-09 v2

Abstract

We analyze the consistency of a recently proposed real tachyon vacuum solution without square roots in open bosonic string field theory. We show that the equation of motion contracted with the solution itself is satisfied. Additionally, by expanding the solution in the basis of the curly L0\mathcal{L}_0 and the traditional L0L_0 eigenstates, we evaluate numerically the vacuum energy and obtain a result in agreement with Sen's conjecture.
